UMBRELLA ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 454,395, dated June 16,1891. Application filed February 19, 1891. Serial No. 382,020. (Nomodel.)

To all whom it may concern.-

Be it known that I, HUGO BLASSBERG, a subject of the King of Prussia,residing at WVald, Province of Rhenish Prussia, in the Kingdom ofPrussia and German Empire, have invented new and useful Improvements inUmbrella-Jens, self-acting through a spring, of which the following is aspecification.

For the purpose of holding the ribs of u inbrellas movable or slidablebells or holders have heretofore been used which are either subjected invarious ways to the action of a spring or are movable along a bushing or001- lar secured to the umbrella-stick.

This invention relates to a bell springing into itself, as shown in theannexed drawings, in which- Figure 1 is a longitudinal section of thebell or holder. Fig. 2 shows a side elevation of the bell or holder.

The bell or holder consists of a compressible spirallybonvoluted metalstrip a, which at the narrowest Winding is fastened to the stick and atthe other end at n,Fig. 2, at the largest winding is riveted togetherand embraces the umbrella-ribs r. The bell thus formed can be shortenedto release the ribs, since by pulling upward at the lower end thewindings slide into one another,whereby the edge passes away from therib ends. By reason of its elasticity the bell on being released resumesits original length.

In addition to a neat appearance and durability, the bell is ofadvantage, since it can be made cheaply, handled readily, and securedeasily in place. Furthermore, it is readily fitted to diiterentthicknesses of stick, since the narrow winding embracing the stick canbe readily widened by distension to fit thicker sticks or contracted bybeing turned or wound to smaller diameter to fit thinner sticks. Theumbrella-stick is indicated by the letter .9.

I am aware that an umbrella-tip has been composed of a cupshaped tubeinclosing a spring and adapted to yield for releasing the tips; but suchdoes not constitute my invention.

I am also aware that a convoluted spring is not of itself novel, andsuch therefore I do not broadly claim.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The combination, with the ribs and stick of an umbrella, of acompressible rib-holding bell consisting of a spirally-convolutedelastic strip having one extremity rigidly attached to the stick and theopposite extremity riveted to a convoluted part of the elastic strip forpreserving this portion in proper form to surround and inclose the tipsof the ribs, substantially as shown and described.

In testimony whereof I have hereunto setmy hand in the presence of twosubscribing witnesses.

HUGO BLASSBERG.
